I have posted a minor update to the plugin which incorporates the most popular feature request, to have the list sorted in reverse order (i.e. most run first).
Also, I have added what might be a fix to the timezone issue. If the error occurs again, please email me your debug logging so I can diagnose further.
Update 24/01/2013: More bugs fixed with the timezone issue. Hopefully fixed now. Please try v1.44.
